MATLAB: Element Wise Multiplication for varying matrix sizes

arithmatic operationelementary operationsMATLAB

Hi.. Is there anyway i could do an Element Wise Multiplication of an array of 24 by 14 to 1 by 14? I need all 24 Rows to be multiplied element-wise to the other single row matrix.

If it can't be done, how should i modify my matrix to perform this operation?

Thanks!

FirstMatrix .* repmat(SecondVector, size(FirstMatrix,1), 1)

MATLAB: Element wise multiplication (beginner)

c is a 1x7 row vector (built with spaces or commas separating the elements)

d is a 7x1 column vector (built with semi-colon separating the elements)

So you need to convert one to the other shape first. E.g.,

c(:) .* d  % The (:) notation converts c into a column vector
